Answer: A pair of inverse operations is defined as two operations that will be performed on a number or
variable, that always results in the original number or variable. Another way to think of this is
that the two inverse operations “undo” each other. For example, addition and subtraction are
inverse operations since we can say
x x 2 2 . If we start with x, then add 2 and subtract 2,
we are left with the original starting variable x.
There are several inverse operations you should be familiar with: addition and subtraction,
multiplication and division, squares and square roots (for positive numbers), as well as cubes and
cube roots. The following examples summarize how to undo these operations using their
inverses
Step-by-step explanation:
6x=shelia total deposit
<span>
<span>
</span>
5y=sherri total
</span><span>
<span>
</span>
sheri is 10 more than shelia so
</span><span>
<span>
</span>
y=10+x
</span><span>
<span>
</span>
and also they deposed same amount total
</span><span>
<span>
</span>
6x=5y
</span><span>
<span>
</span>
6x=5(10+x)
</span><span>
<span>
</span>
6x=50+5x
</span><span>
<span>
</span>
minus 5x both sides
</span><span>
<span>
</span>
x=50
</span><span>
<span>
</span>
y=10+x
</span><span>
<span>
</span>
y=10+50
</span><span>
<span>
</span>
y=60
</span>
<span>
</span>
shelia deposits $50 each and sherri deposits $60 each
50*6=300
60*5=300
300=300
ok answer to questions
Write an equation. Let x represent the amount of one of Sheila’s deposits. and y is the other one, 5x=6y, y=10+x
⦁ Solve the equation. Show your work. see above
⦁ Check your solution. Show your work.
⦁ State the solution in complete sentences. Shelia deposited $50 each time, Sherri deposited $60 each time
Being multiplied by 5 every time. Answers are a=250 b=1,250 c=6,250
